IMPROVEMENT IN CARRIAGE-DOOR LOCKS.

Specification forming part of Letters Patent No. 197,215, dated November20, 1877 application filed September 28, 1877.

To all whom 'it may concern Be it known that I, ,TosIAs D. Goon, ofMount Joy, inthe county of Lancaster and I State of Pennsylvania, haveinvented certain ters of reference marked thereon, and a brief 1description, will enable those skilled in the art In the drawings,Figure 1 is a perspective view of the, several parts detached. Fig. 2shows the plan of the interior and arrangement of the parts. i

This lock or latch is to be set into a mortise so asto bring the selvageor edge plate at flush with the wood on the edge of the oor.

The'bolt and its operation are as in other locks and latches. It isoperated withaturning knob or handle inserted into the tumbler F, sothat its lever-arm f, prolonged on one side of the circular centralenlargement, forms shoulders, against which the upper and lower plates 0D set and confine it. in its turning motion. This lever-arm f strikesthe pendent arm eof the bolt E, in order to press it back against thespring K to release it from the catch-plate H, ioopen the door in theordinary manner.

The novelty of my invention consists in the combined casting of theedge-plate A with the end flanges B B, pins z, and bottom plate so as tocontract the parts, I use a simple flat or steel wire spring, K, so setdown between the oblique flanges G and bent as to have its upper enddirectly bearing, against the back part of the bolt E, which has agroove on its under side, that fits over the, guide-ledge N, to hold itdirect in its movement back and forth. I

This is an arrangement that results in a much narrower case, so simpleas to be much cheaper than, and equally as good and durable as, thosenow in use, while it supplies an article much wanted in panelcarriage-doors having narrow frames.

The catch-plate H is also improved by be-.

ing boxed out centrally at h, so as to form an inclined plane, J, forthe beveled end of the bolt, which inclined plane is terminated by anopen oblong slot, I, into which the bolt is shot by the spring 0, andsustains the front of the door. Thus it relieves the strain on thehinges, so injurious when the ordinary inclined catch is used, withoutany support to the vertical action or play of the bolt.

The tumbler F may have a square opening for any kind of a handle, L, orknob, to turn the bolt in order to open the door; or it may be adaptedfor a key, M, if desirable.

This combination can be applied to a right or left hand door.

I am not aware that there is an article of the kind to be had thatsupplies the carriagemakers wants as does this compact, narrow, andcheap combination, arranged as shown and specified.

I claim it as a new article of manufacture, resulting from the specificarrangement in the design of its parts, taken as a whole. In otherwords,

I claim- The combination of the faceplate A, and back and side plates,when cast in a single piece, and furnished with guide ledges N, obliqueflanges G G, single bent spring K, working at one end against thedepending portion of latch E, the whole; arranged and operatingsubstantially as and for the purpose specified.
